BOOK-HOLDER.

Specification of Letters Patent.

Patented Dec. 30, 1919.

Application filed May 23, 1919, Serial No. 299,148.

To all whom it may concern:

Be it known that I, TRUMAN W. GEROULD, a citizen of the United States, and a resident of Athens, in the county of Bradford and State of Pennsylvania, have invented certain new and useful Improvements in Book- Holders, of which the following is a speci fication.

My invention is an improvement in book holders, and has for its object to provide a device of the character specified especially adapted for use in holding books in open position, as, for instance, music books, to be held open on the rack of a piano during singing or playing, wherein the book is so held that the pages exposed are in approximately the same plane and without danger of the loosening of the leaves or of the book.

In the drawings:

Figure 1 is a front view showing the holder in use;

Fig. 2 is an end View;

' Fig. 3 is a perspective view, looking front below.

In the present embodiment of the invention, a pair of clamping jaws 1 and 2 is provided, each of which is substantially U-shaped, comprising a body and arms extending at substantially right angles to the body.

Each of the arms of the jaw 1 is provided at the end remote from the body with an angular bend 3, and at the end of the bend each arm has an eye 4. Oneof the arms has an extension 5 beyond the eye, the said extension being an open loop, as shown.

One of the arms of the aw 2- has an outwardly extending journal pin 6 which engages the eye 4 on the adjacent arm of the jaw 1. and the other arm of the jaw 2 has a similar journal pin 7 which engages the eye 4 of the other arm of the jaw 1..

This journal pin has an inwardly bent stop 8, andthe said stop is adapted to be engaged by the loop 5 of the jaw 1, to limit the movementbf the jaws with respect to each other to the position shown in 2-. Both of the aws are formed from wire of suitable gage bent to shape and the book, indicated at 9, as, for instance, a folio, is

opened at the proper page and inserted between the jaws.

The engagement between the stop 8 and the free arm of the loop 5 limits the swinging movement of the jaws away from each other, providing thus an adjustment. It will be understood that the loop 5 is resilient to a certain degree. The farther the jaw 2 swings away from the jaw 1, until the jaw 2 is approximately at right angles to the jaw 1, the more tightly is the engagement between the stop 8 and the loop 5. hen, however, the jaw 2 swings beyond a position at right angles to the aw 1 the reverse is true, the engagement between the stop 8 and the loop 5 becoming less close. This is a feature of importance, as otherwise it would be necessary to hold the jaw open with the hand during turning of the leaves. When in place on the book, the book is firmly held against closing movement and may be placed on the music stand in the usual manner, requiring no additional sup port,

I claim:

A book holder comprising a pair of jaws of U -shape, one jaw having its arms of greater length than the other and being adapted to engage against the back of a book, the jaw with the shorter arms being engageable with the open side of a book, both arms of the larger jaw being inclined at their end portions toward the smaller jaw and one arm of the larger terminating in a loop and the other jaw thereof being formed adjacent its end portion with a corresponding loop and having its terminal upwardly and then downwardly curved to be disposed adjacentone arm of the smaller jaw, the smaller aw having the end of one arm formed with a lateral extension journaled within said first named loop and having its other arm laterally extended and journaled through said second named loop with its terminal rebent to extend toward the first named arm of the smaller jaw in position to engage the terminal portion of the second named arm of the larger jaw.
